Which issues? :)

Do you see me flaming? :) The process you see is what it is, the rails are sanded a bit before. I challenge anyone to do it faster and more feasible , cleaner, etc etc. ;)

You can do 1,2,3 with PU. Actually, the epoxy is brittle. The elongation break for epoxies (cheap ones), is way less than PU (shore 90). The PU gives you impact protection as per production boards. Not to mention cost coz PU is way less expensive.

How many bubbles you've got in the rails? That's probably more near wood line simply because this is where air is trapped and degassing (epoxy produces heat, heat will expand air bubbles). There is no way to control this. The air void can be trapped inside no matter what.

The premade PU rails eliminate this, as you see, it's very tight channel. For sure I'm using similar for inserts and fins.
And, it is highly repeatable, which diy pouring is simply not. Forget about the abs, it's too expensive and too much work.

D.
I agree thst looks so clean.Three questions:
1.Where do you find them (PU strips) in that shape...?
2.Did u ever had any issues in the connection of the strips? 3.When shapping..rooted do you have melting of material?

Now for my input in pooring Epoxy in channels...
If the resin epoxy has low viscosity it will go in the porous and everything willbe ok..also unfortunatelly for the messy issue, a good way that iused,was to use the vibration of the phone on the pawlonia sheet and u will see the level going down and more bubbles on the surface ....more epoxy more expensive...yeah i know...but works ok as all the bubbles come on surface that is gonna get shaped/shanded..leaving a perfect surface. Brittlness is quite another issue...there is way to avoid of that ....but is something that I still monitor in a trial board..
But In case you hit the brittle rail ...this is probably fixable....what happens with the PU??
ha, ha

I am asking you which issues?! Since you've mentioned there are issues I would love to hear before I answer :)

Remember, all boards (except some 'weirdo' brands) , snowboards in particular, have a PU rails. Again, before continuing, ask yourself why? So, what does happen with production boards when hit a PU? ;)
Ha ha ..I am already talking about the issues i.e.

Pros: easy apply to any outline espesially tips, colours, easy shapping/sanding/Rooting without melting as abs

cons;messyness..more time...high cost and the britleness..is in your favour in matters of repairness..

I will show how it will be done after shapping...next board will be with abs...That already have...and know the process....BUT pls tell me about below as I agree thst looks so clean and easy y to apply..Three questions:
1.Where do you find them (PU strips) in that shape...?
2.Did u ever had any issues in the connection of the strips? 3.When shapping..rooted do you have melting of material?

The PU is not ABS.

1. I've made them, and this is well documented on the provided link. As said, all rails are exactly the same, it's repeatable process with high accuracy. Once you made them there is no going back to pouring and wasting time/materials etc.
2. No, the PU can be glued with any PU glue, or epoxy. Again, look at the production boards.

:D Sweet!
Is that carbon on the ends? Looks like it's ready for a Madmax movie

Yes it is. There are actually. Three different carbon used ..and that's the reason for her name...CARBON CUBED..:) bottom Carbon and glass aswell ...
She is so flexy...so nice!!

Find a car panel beater supplier, look for ABS spools for plastic panel repair. Then use a clothes iron over aluminium foil to flatten the ABS wire into your mould.
